Strengths: Durability. ( I suppose when maintained and installed correctly.)

Weaknesses: For me none.

Bottom Line:

After reading the other reviews Im shocked. I have well over 5,600 miles on my 6600. Its not that I'm cheap I have a new one still in the box. I have just been waiting for it to give me a reason. Still shifts great. I've never babied it. I might clean it once a week with simple green and triflow.

There is nothing wrong with this chain. Although Shimano has come out with a new Ultegra chain, the 6600 still has its merits. I have over 2000 miles on mine, with a lot of mountain climbing, and it shows not a hair's width of stretch. Still shifts great and is silent. Seems that cyclists like to pan components that wear out (tires, chains, tubes). I am sure there are a few lemons out there but this is a good chain and it does not deserve a bad rap.

Weaknesses: Tends to make a ticking sound. My current chain did this after 30 miles until I lubed it, then was quiet until now--about 1600 miles.

Bottom Line:

The chain is light weight and shifts well. Not as long lived as 8 speed. Has a tendency to make a ticking sound. My first chain lasted for 1900 miles, but ticked a lot. The current chain has almost 1600 miles on it and just stated ticking when I pedal. I keep it clean and check wear with a Park chain tool.

Weaknesses: short life, not durable, Near impossible to repin onto after taking out a pin.

Bottom Line:

This chain ran fairly smooth and quick for a while but after about 1500 miles you could tell it was stretched a bit. The real problem came when I swapped my frame and tried to use this chain again. It immediately started to creak and moan everytime I put some force on it.
